CARL PFEIFFEE, OF ST. LOI IIS, MISSOURI.

SHOE-JACK.

To all whom it may concern:

Be it known that I, CARL PFEIFFER, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented new and useful im- 'provements in fihoe Jacks, of which the following is a specification.

My invention relates particularly to shoe-jacks used in repairing the arrangements and combinations of parts shoes.

The principal object of my invention is to provide a device which can be easily adjusted to hold a. shoe firmly in the difi'erent positions in which it is desirable to place a shoe while repairing it.

' The invention consists in the parts and in In the shoe-jack shown in the accompanying drawing, a shoe to be repaired is fitted loosely on the last 1 which is fixed to the up per end of a standard. The standard consists of a base section 2, a swivel section 3, a hinged section 4: and a head section 5. The base section 2 is preferably tubular, and integral therewith at the bottom is a base 6 which is fastened to the floor. The

upper portion 7 of the base section 2 is smaller in diameter than the rest of said base section. The swivel section 3 is also tubular, and its lower end portion fits over the upper portion 7 of the base section 2. A thumb screw 8 passes through the lower end portion of the swivel section 3 and engages the upper portion 7 of the base section 2. Projecting upwardly and outwardly from the swivel section is a bracket 9 which terminates in a cylindrical head 10.

In the upper end of the swivel section 3 is a socket 11, in which is fitted a disk 12 of some. resilient material, such as rubber, or

- the like.

The hinged section 4 is tubular, and its the socket 11 in the up- Specification of Letters Patent.

downwardly and outwardly from the hinged section 4: is an arm 13, which is bifurcated at its outer end to form two branches 1%.. 'lhe two branches 1 1 of the arm 13 straddle the head 10 of the bracket 9, and through the two branches 14: and said head 10 passes a pivot bolt 15. In each side of the head 10 is a circumferential recess 16. On each branch 14: of the bifurcated end of the arm 13 is a lug 17 which PIOJECtS inwardly and enters the corresponding recess 16.

The head section 5 is hollow and its lower end portion fits into the upper end portion of the hinged section 4. A thumb screw 18 passes through the upper end portion of the hinged section 4 and engages the lower end portion or the head section 5. The upper portion of the head section 5 tapers and in its upper end is tightly fitted the last 1. Within the head section 5 are two spaced horizontal partitions 19, in which are vertically alined holes 20. Through the holes 20 passes a round rod 21 which has teeth 22 along one side. =Meshing with the teeth 22 on the rod 21 is a gear 23 which is loosely mounted on a horizontal pin Zd'secured in the head section 5. A lug 25 which is preferably integral with the head section 5 pro- 'ects inwardly on each side of the gear 25. in the wall of the head section 5 is a slot 26 located. in the plane of the gear 28. Extending along each side of the slot 26 is a bracket 27 which is preferably integral with the head section 5. To the brackets 27 a lever 29 is pivoted by a pin 28. The lever 29 is provided with teeth 30 arranged concentrically about the pivot pin 28, and these teeth 30 mesh with the teeth of the gear 23. The outer edge of one bracket 27 is curved concentrically with the pivot pin 28 and has ratchet teeth 31 cut therein. Pivoted to the lever 29 is a pawl 32 which engages the ratchet teeth 31 on the edge of the bracket 27. A spring. 33 presses the pawl 32 into engagement with the ratchet teeth 31. To the upper end of the rod 21 is pivoted a curved link 34 which extends through a slot 35 in the wall of the head section 5 and vertically I along the outside of the head section 5. The er end portion of the link 31'l1as a hooked end 36 which overlies the middle portion of the last-1. A cover plate 37 allows access to the inside of the head sec tion 5.

In using the device, the pawl 32-is pressed and drawn out of engagement with the teeth 31 on the bracket 27 and the lever 29 is raised. The motion of the lever 29 is transmitted through the gear 23 to the rod 21 and the link 34 is shifted upwardly. The link 34 is swung out from the head section 5, as shown in dotted lines in Fig. 1. The shoe is then placed on the last 1 and the link 34 swung back into its normal position. After the shoe is adjusted on the last 1 to the desired position, the lever 29 is pushed downward and the hooked end 36 of the link 34 is drawn tightly against the shoe to hold it firmly in place. The pawl 32 engages the teeth 61 of the bracket 27 and ing the lever 29, the pressure holds the lever 29 against upward movement. By releasing the pawl 32 and raisof the hooked end 36 of the link 34 upon the shoe can be I The released'and the shoe can be adjusted to another position.

To turn the last 1 around on a vertical axis to any desired position, the thumb screw 18 is loosened and the head section 5 turned relatively to the hinged-section 4. The head section 5, together with the hinged section 4, can be tilted about the pivot bolt 15 to an angular position. The lugs 17 contact with the ends of the-recesses l6 and limit the amount of tilting movement. While the head section 5 is tilted, the last 1 can be turned on its axis to any position by loosening the thumb screw 18 and by turning the head section 5 relatively tothe hinged section 4. Also, while the head seetio'n 5 is tilted, the thumb screw 8 can be loosened and the head section 5 together with the hinged section 4 and the swivel section 3, can'be turned about a vertical axia'relative to the base section 2. The re silient disk 12 acts as a cushion and prevents -"the-shock of hammering upon the last 1 from injuring the parts.

particular construction which is shown may be considerably modified with out departing from the invention, and I do'not wish to be limited to the. details of this .particular construction.

What I claim is: L'A shoe-jack comprising a vertical standard, the upper portion or said stand ard to move vertically,

ard being jointed to the lower portion of said standard to swing on a horizontal axis, the upper portion of said standard above said joint and the portionnof said standard below said joint each consisting oi two sections swiveled together to turn on a vertical axis, the upper section of said standardbeing hollow and having a last secured to the upper end thereof, a movable rod having a hooked end overlying said last, said h )per section having a slot therein through which said rod passes, a rack bar slidably mounted in said upper section to move vertically and pirotally connected to said movable rod, a lever pivoted to said upper section, and

gearing operatively connecting said leverand said rack bar.

2. A shoc-jack comprising a hollow standard, a last secured in the upper end of said standard,'a rack bar mounted in said standard to move vertically, a rod pivotally connected near its lower end to said rack bar and having its upper end portion hooked to overlie said last, said standard having a slot therein through which said rod passes, a lever having a circular head with gear teeth thereon and pivoted on said standard, a gear journaled on said standard and meshing with said rack bar and with the gear teethof said lever, and releasable means for preventing upward movement of said lever in its diiferent positions.

3. A shoe-jack comprising a hollow standard, a last secured to the up er end of said standard, a rack bar mounted in said standa vertically movable rod pivotally connected at its lower end to the upper end of said rack bar, said rod having its upper end hooked to overlie said last, a lever pivoted on said standard, gearing connecting said rack bar and said 1' .er, and releasable means for holding said lever to revent upper movement of said rod.
